In regard to the Y2K scare; the fear was caused because of a hard-coded clock design in IBM systems that could not accept dates beyond 12/31/1999; that issue was avoided by a combination of physical and logical upgrades to the systems that were affected by this limited thinking design.
Any assumption is just that, an assumption; and to do so can cause people to be poorly prepared for the future. If someone poses a question about what could happen if the sun were to cross a powerful magnetic band; it would be best to answer the scientific question with a scientific reply. There are many possibilities of things that could happen if such an event were to occur, and no living person has all of the answers. Perhaps such an event could cause the earth's poles to swap, or perhaps there would simply be a slight increase or decrease in the earth's gravitational pull. It is more about the process of considering all of the possibilities than debating the proposed event. This is the essence of science itself, to postulate the "what if" and propose all of the possible results.

<<In astronomy, the local standard of rest or LSR follows the mean motion of material in the Milky Way in the neighborhood of the Sun. The path of this material is not precisely circular. The Sun follows the solar circle (eccentricity e < 0.1 ) at a speed of about 220 km/s in a clockwise direction when viewed from the galactic north pole at a radius of ≈ 8 kpc about the center of the galaxy near Sgr A*, and has only a slight motion, towards the Solar apex, relative to the LSR. The LSR velocity is anywhere from 202–241 km/s.>>
A solar eccentricity e < 0.1 means that:
the minor axis is nor more than 0.5% smaller than the major axis.
That comes pretty damn close to being a circle.

Gee, i wouldn't have thought that a discussion about "Fluff" would bring so much doom and gloom.
But just to throw my two cents worth in, i just heard someone on TV mention that Saturn would be leaving the house of Jupiter around the end of 2012.
Many years ago i caught the end of a PBS program that was showing a really ancient chinese calendar that had spikes on it that correlated with events that happened on the Earth. The biggest spike was at the time of Krakatoa. The calendar ended in 12/2012. Then the program ended.
I listened intently to hear what the program was or when it would play again, but there was no mention. I checked PBS carefully for the next couple of weeks, but could not find any program anywhere that listed anything about an ancient Chinese calendar. So for me--THAT is a big mystery.

The temperature of these ground state hydrogen atoms is defined by their random velocities (~5 km/s). They lack a mechanism to radiate even if they collided with one another at their mild energies of a half an electron volt (which is highly unlikely in any event).

Black bodies radiate away their energy but transparent bodies DO NOT.


Even the earth's troposphere is full of gases that are highly transparent in both the visible and the infrared (e.g., nitrogen, oxygen, & argon). The troposphere can thermally radiate ONLY through the intermediary of trace greenhouse gases like carbon dioxide, water and methane.

Is there some reason why we dont call all that fluff what it really is, Plasma, the 5th state of matter.
"Local Fluff" contains a wispy mixture of hydrogen and helium atoms at a temperature of ~6000 K.

Hence, these atoms have a thermal energy kT of ~ 0.5 eV. [k ~ (1 eV/12,000 K)]

It takes 13.6 eV (~ 27 kT) to ionize a hydrogen atom (and much more to ionize helium).

Plasmas are electrically neutral overall.

However, movement through a magnetic field will induce currents.

There was rational reason to be worried about computers crashing at the end of the 20th century. That they didn't was some combination of miscalculation, careful preparation, and luck. But there is no rational reason at all to think that doomsday will come in 2012. The funny thing is, even the Mayans didn't think that! It's just the New Age kooks misunderstanding the Mayan calendar.
You may be right Chris; but I never did buy into the millennium computer scare. I figured it would pass; and it did. So maybe I was just lucky. :) Any way; I get tired of hearing about all the doomsday and end of world prophesies. :cry:
